From: Manoj Iyer <manoj.iyer@canonical.com>
In the latest V-series bios DMI_PRODUCT_VERSION does not contain the string Lenovo or Thinkpad, but is set to the model number, this causes the thinkpad_acpi module to fail to load. Recognize laptop as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.
